Abstract

The invention relates to combines for driving underground mines. The goal is to increase the productivity of soil poddirki. The mining harvester includes a chassis 1, a slewing column 2 with an arrow-shaped executive body 3. The latter consists of a handle (P) 4 and a boom body (K) 5 pivotally connected to it (K) 5. For vertical movement of K 5 and R 4, the combine is equipped with hydraulic cylinders (HZ) 6 and 7. At the same time, HZ is located below the boom 3. Installed K 5 in the guide beams 8 can be moved along them through the HZ telescope 9. To fix the position of the boom 3 on HZ 6 and 7 are installed removable stops 10 and 11. The size of the stop 10 is selected from the installation condition K 5 parallel to the soil of the mine. The size of the anvil 11 is determined by the required depth of the subframe. 1 il.

WITH

The invention relates to the mining industry, namely to combines for the driving of underground mine workings.

The purpose of the invention is to increase the productivity of the combine when undercutting the production soil.

The drawing shows a general view of the combine.

On the undercarriage 1 of the mining combine, a turntable column 2 is mounted with an arrow-shaped actuator body 3 consisting of the handle 4 and the boom body 5 pivotally connected to it. For vertical movement of the housing 5 and the handle 4, the combine is equipped with hydraulic cylinders 6 and 7. At the same time, the hydraulic cylinder 7 of the vertical movement of the handle 4 is located

under the boom and pivotally connected at one end with the housing 5, and the other with the arm 4. The housing 5 is installed in guide rails 8 with the ability to move through them through the telescope hydraulic cylinders 9. For fixing the position of the swept actuator 3 on the hydraulic cylinders 6 and 7, interchangeable stops 10 and 11.

Mining harvester works as follows. When performing the operation of undercutting the soil of a mine working, the body 5 by means of the anvil 10 mounted on the hydraulic cylinder 6 is fixed in a position in which the guide rails 8 and the body 5 are parallel to the production soil. Then, the handle 4 is lowered and the baffle bit is sunk into the working soil to a depth. depending on the size of the removable stop 11.

If it is necessary to increase or decrease the depth of the subframe, they change the length of the interchangeable stop 11. By rotating in a plane parallel to the soil of the swept actuator body 3, the soil is picked up over the entire width of the excavation. After that, the cylinders 9 of the telescope along the guide beams 8 carry out the boom in the direction of the sub-rider. Fixing the position of the hull 5 parallel to the soil of the mine provides a constant penetration of the fender crown into the soil of the mine.

The proposed implementation of the combine makes it possible to exclude additional operations associated with changing the position of the boom when picking up the soil of mine workings.

Claims (1)

Claims of the invention: A mining combine including a running gear, a slewing column. An arrow-mounted actuator with a handle, hinged on the boom housing, guiding beams with telescope cylinders and cylinders for vertical movement of the case and arm, characterized in that, in order to increase the productivity of the mine excavation soil, the hydraulic cylinder of the vertical movement of the boom body is provided with a removable stop for fixing the hull parallel to the soil of the mine, and the hydraulic cylinder of the vertical movement of the handle is installed under the boom and is also equipped with a replaceable stop for limiting the depth of the hammer. ; /
